Twenty-seven individuals of Stenopsyche from An-hui, Shan-xi and Si-chuan provinces, China, were examined and their DNA (mtCOI) sequences were extracted and analyzed. The larva, male, and female of a new species, S. huangshanensis sp. nov., associated by mtCOI gene sequences, are described and illustrated. Larvae and adult females of 3 known species, S. angustata Martynov 1930, S. navasi Ulmer ...

Five species of the genus Pseudodiaptomus, P. inopinus, P. poplesia, P. marinus, P. nihonkaiensis, and P. sp. occur in Korea nearshore waters. Although the four species except for P. sp. have been classified into Lobus and Ramosus groups, two for each group, based on morphological characters, this classification had yet to be confirmed by molecular characters. Here, we determined molecular char...

We studied population genetic differentiation in the sympatric Sonoran Desert cactophilic flies Drosophila pachea, D. mettleri and D. nigrospiracula across their continental and peninsular ranges. These flies show marked differences in ecology and behaviour including dispersal distances and host cactus specialization. Examination of a fragment of the mitochondrial cytochrome oxidase subunit I g...

Recent studies from East Asia and Canadian National Collection of Insects have established the utility of DNA barcoding technique in identification of true bugs. The present study is an expansion of the database by adding mitochondrial cytochrome c oxidase I (mtCOI) sequences from forty three species of indigenous true bugs of India. mtCOI gene analysis of infraorder Pentatomomorpha covering a ...

Centropages mohamedi sp. nov. (Copepoda: Calanoida) is described from specimens collected in zooplankton samples off Obhur Creek on the Saudi Arabian coast of the central Red Sea. The new species is most closely related to C. orsinii Giesbrecht, 1889, a species described from the Red Sea and widely distributed in the neritic waters of the Indo-West Pacific region. The new species is mainly dist...

Six new species of Endotribelos from Brazil are described and illustrated as male, female, pupa and larva: E. bicolor sp. n., E. fulvidus sp. n., E. jaragua sp. n., E. jiboia sp. n., E. semibruneus sp. n. and E. sublettei sp. n. The female of E. calophylli Roque & Trivinho-Strixino and the larvae of four unknown morphotypes are also described. Keys including males and larvae of all known specie...

East Antarctic octopods were identified by sequencing mtCOI and using four analytical approaches: Neighbor-joining by Kimura-2-Parameter-based distances, character-based, BLAST, and Bayesian Inference of Phylogeny. Although the distance-based analytical approaches identified a high proportion of the sequences (99.5% to genus and 88.1% to species level), these results are undermined by the absen...

The soybean stem fly, Melanagromyza sojae, an Asian native insect, has successfully established in Brazil, Argentina, Paraguay and Bolivia. These countries are among the lead global producing nations, being collectively known as belt of South America. Infestation levels M. sojae grow by year, facilitated lack efficient management strategies. Previous studies have revealed a high number maternal...
